3 Claims.

This invention relates to treatment chairs and has for an object to provide an improved construction adapted especially for -use in beauty parlors or similar establishments though it is capable of use in the home or other Iplace.

Another object of the invention is to yprovide a tiltable chair wherein the operator may readily tilt and lock the chair in various desirable positions.

A further land more specic object of the invention is to provide a tiltable chair having a stationary base and tiltable body with means including a hand-actuated structure arranged so that it will require 1a minimum amount of power to tilt the chair either when empty or when occupied.

In the accompanying drawings- Fig. 1 is a side view of a -chair disclosing an embodiment of the invention;

Fig. 2 is a rear View of the chair shown in Fig. 1 .with certain parts broken away for illustrating certain detail structures;

Fig. 3 is an enlarged side View of the adjustable mechanism shown in Fig. 1;

Fig. 4 is a sectional View through Fig. 3 approximately on the line 4-4 Fig. 5 is a transverse sectional view throug Fig. 3 approximately on the line 5--5;

Fig. 6 is a sectional view through Fig. 2 approximately on the line 6 6, the same .being on a somewhat enlarged scale.

Referring to the accompanying drawings by numerals, I indicates a base which may have any number of legs 2 for supporting the base at the desired height. The base I is provided with a straight surface 3 and an inclined straight surface 4. The surface 3 is preferably parallel with the iioor or surface on which the legs 2 rest, while the surface 4 is at an angle. As illustrated in Fig. 2, the base I includes not only the side members I' and I", but a comparatively strong .bracing bar 5 rand, if desired, :a second bracing bar 6. These .bars have their ends embedded in the members I and I". The ends just mentioned may .be held in place by any suitable means, as for instance, nails or screws, bolts, or adhesive. In actual use it has been found that `a good grade of glue is very satisfactory. The bracing bar 5 is provided with a squared section 'I so that the bracket 8 may be rigidly secured thereto by suitable screws 9. One end of the respective links I0 is lpvota-lly connected to the stud I I of bracket 8 rwhile the opposite end is secured to the free end of an arm I2 which may be formed integral with or rigidly secured to rock shaft I3. The

rock shaft I3 extends through and is pivotally mounted in the respective ears I4 of the respective anchor plates I5. As shown in Fig. 2 there vare provided two brackets or anchor plates I5. Consequently, there are provided two ears I4 acting as .journal members for the rock shaft I3. A collar IS is pinned or otherwise rigidly secured to shaft I3 at one end and a hub Il is pinned or otherwise rigidly secured to shaft I3 at the opposite end. The hub Il merges into an arm I8 hereinafter fully described.

'I'he respective ears I4 are ,carried by the respective anchor plates I5 as shown in Fig. 6 and these plates are yconnected by screws or other suitable means to the respective side members 20 and 2| of the chair -body 22. The body 22 is provided with a lleg rest 23 and back 24. The leg rest 23 merges into what may be termed a seat 25. If desired, the body 22, could have arms 26 though this is not essential.

As shown in Fig. 6, the respective anchor plates I5 are rigidly secured in place by suitable screws and arranged so that the respective ears I4 depend from the lower surface of the body 22. Also there `are provided anchoring ears 2l pivotally :mounted on the body members I and I. The pivotal mounting may be bolts, pins or other desirable means, but a strong screw 28 has been found to be a desirable form of pivotally mounting the anchor plates on the frame I.

While the various parts may be made of any suitable material, preferably the body I is made of wood and also the side members 20 and 2I of body 22. The bracing bar 5 is also formed of wood but the rock shaft I3 is preferably formed of metal as well as the plates I5 and ears projecting therefrom.

Rigidly secured by screws or otherwise to the wooden side members 2I is a quadrant 29 which is preferably of metal. This quadrant has an arc-shaped rack 3| at one end and at the other end a depending ear 30 loosely surrounding shaft I3. Arm I8 is shown in detail in Figs. 3 and 4 and from these figures it will be seen that the arm has a bifurcated portion 32 through which a pivot :pin 33 extends. The pin or bolt 33 also extends through the offset end 34 of the handle or hand-actuated member 35. The offset end 34 is provided with a strong central tooth 33 which is adapted to be inserted between any of the teeth 31 of the rack 3|, as shown in Fig. 4, when it is' desired to lock the body 22 in any desired adj-usted position. To prevent the arm I8 and body 22 from springing or moving apart, the free end of arm I8 is provided with aA hook member 38 L which may be intgeral with the arm or made separate and rigidly secured thereto.` The hook member 38 extends over and back of the rack 3| so as to prevent separation of the respective members.

When the parts are in the position shown in Figs. 1 and 4, the body 22 is locked against swinging movement. If it should be desired to swing the body 22 in either of two directions, the handle 35 is swung on pin 33 until it extends upwardly and then the handle is used as a lever to swing the parts to the desired new position. After having been swung to the new position, the handle 35 is swung downwardly to the position shown in Figs. 1 and 4, whereupon the parts will be locked against further movement. When the handle 35 and the arm I8 are swung, the rock shait I3 will be moved correspondingly and the arm I2 also will swing. This arm acts against the links IG to provide a relative pull or push to swing body 2,2. If desired, the operator may grasp the upper end of back 24 during the swinging movement to secure the exact adjustment desired and the'n handle 35 is swung downwardly to its locked pos"ition. By reason of the ilat surfaces 3 and Il as shown in Fig. l, the body 22 can be swung only to a horizontal position or to an inclined position equal to the inclination of the surface `lil. If it should be desired to have a greater movement it will be necessary to make the surface 4 at a greater incline and also to lengthen the rack 3l. It will, of course, be understood that the surface 4 may be at any desired angle with respect t'o surface 3 and also the rack SI may be of any desired length though the proportions shown in Fig. 1 have proved to be satisfactory in the market.

1. A chair of the character described including a base, a body having a seat portion, means for pivotally mounting said body on said base so that the Abody may vswing fback and forth -in a given plane, and means for swinging said body, said means including an arm mounted on said body to swing in an arc, means actuated by said arm presenting a toggle structure acting on said body and said base for tilting the body in respect to the base when said arm is swung, a handle pivotally connected to said arm for actuating the arm, said handle having an offset end providing a tooth, and a quadrant rigidly secured to said body positioned near said arm, said quadrant having a rack arranged in an arc and positioned to receive the tooth on said offset end when the handle is moved to a given position for locking said arm against movement.

2. A chair as set forth in claim 1, characterized byl having a hook member carried by the free end of said arm positioned to extend over the outer edge offset from the inner face of said quadrant and in back of said edge for preventing separation of the quadrant and arm when the handle has forced the tooth of said offset Yend between certain teeth o'f said rack.
